Problems solved by technology

But there are also some obvious deficiencies, such as flame retardancy. If polyvinyl chloride plastic is used as the substrate, although it has certain flame retardancy, such materials will release a large amount of toxic and harmful halogen gases during combustion or smoldering. It

Abstract

An efficient flame-retardant plastic-wood composite board is prepared by compounding plastic particles, maleic anhydride grafted plastic particles, modified wood powder, modified sepiolite, a boron-phosphorus compound flame retardant, baking soda, calcium stearate, terpene resin, white oil and an antioxidant. The preparation method is convenient to produce and manufacture, and is low in productioncost, high in strength and good in flame retardant effect. Compared with a common polyvinyl chloride-based plastic-wood board, the efficient flame-retardant plastic-wood composite board does not release poisonous harmful halogen gas in a burning or smouldering process and does not cause toxic gas damage to surrounding people. Compared with common polyethylene-based and polypropylene-based plastic-wood boards, the efficient flame-retardant plastic-wood composite board has the advantages that efficient flame retardancy is achieved, fire hazard does not occur in a using process of the board, andthe use is safer. The efficient flame-retardant plastic-wood composite board can be widely applied to the fields of transportation, decoration, packaging storage and the like.

Description

technical field [0001] The invention relates to a wood-plastic composite material, in particular to a high-efficiency flame-retardant wood-plastic composite board and a preparation method thereof. Background technique [0002] In recent years, with the enhancement of people's awareness of environmental protection, wood-plastic composite materials with a wide range of raw materials, environmentally friendly, renewable and recyclable materials have attracted more and more attention. Wood-plastic composite materials are made of new / old plastics, straw powder and various additives, and then formed by extrusion, molding or injection molding. The molding speed is fast and the production efficiency is high; the wood-plastic composite materials can be used as pallets and packaging boxes Storage materials such as planks and beams, decoration and decoration materials such as houses, floors, and building templates, outdoor tables and chairs, benches and other leisure materials used in ...
